摘　　要：采用鲁棒H∞控制理论设计了某型飞机的自动着陆控制系统,描述了飞机自动着陆的过程,分析了系统中可能受到的干扰,建立了H∞控制问题的系统增广模型,针对飞机着陆时的要求设计了鲁棒H∞控制器以抑制干扰的影响。仿真结果表明,所设计的控制器对自动着陆时的干扰具有较强的抑制作用,能使飞机准确地跟踪期望轨迹并满足着陆指标的要求,具有良好的动态性能和鲁棒性能。Robust H∞ control technique is employed to develop controller for the automatic landing system for an aircraft. This paper describes the autolanding process. The probably encountered disturbances are analyzed. The enhanced system model is established. A kind of robust controller is designed to make the needs of the special requirements. Numerical simulation presents the designing procedure of the proposed controller and shows that the controller makes disturbance attenuated quite well, and makes the autolanding system to properly follow the expected trace and satisfy the landing requirements, and the controller has good dynamic performance and robust performance.
